To all whom 'it may concern:

Be it known that l, (jimnnus `l PEASE, a citizen ot' the United States, residing at Chicago, in 'the county of Cook and State of Illinois, have invented certain new and use- --lful lmprovelmuits in llluelrint Machines,

of which the followingl is a speeilieation.

My invention relates toa machine'for manufact uring photographic copies of drawings, or the like.

An important object of this invention is to provide a machine of the above character, so constructed that a maximum amount of light may be thrown upon the print and drawing without danger of cracking the transparent printing plate across which such print and drawing,r are, fed.

A further object of this invention is to provide supportingmeans for the transparent printing plate, which will pcrmltrthc same to be moved to a position where said plate may he cleaned.

A further object of my invention is to provide supporting means for the arc-lamps' employed in connection with my machine, where y said arclamps may be swung to-I ward the horizontal so ,that their carbons may be trimmed.

)A further object of this invention is to provide supportlng means for the arc-lamps, i

which also serves as a housing for the wires which supply the current to said lamps,

A further object of my invention is to provide novel means for preventing the endless belt from having undue lateral movement toward one end of its rollers.

A further object of this invention is t0 provide a machine of the above character, so constructed that the print paper and tracing are fed into the same at one side of the machine and the tracing discharged from the machine at the same side, whereby the operator is not forced to change his position when operating the machine.

.A further object of thisinvention is to provide means for slackening the endless belt, whereby the print paper and tracing may be`removed from within the machine without having to pass entirely ther throu h.

A urther object of my invention is to provide novel gearing for positively driving the endless belt.'

A further object of this invention is to provide a blue print machine, the operation of which may be readily controlled by the attendant.

A further object of this invention is yto improve the construction in general of"u machine of this class, whereby the process of making photograhic copies is rendered more expeditious and reliable.

Other objects and advantages of this invention will appear in the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, Figure l is a' front elevation of the machine, Fig. 2 is a central vertical Section through the same, Fig. 3 is an enlarged detail view of the trans mission gear employed uponthe machine, Fig. Ll is an enlarged detail side view of the pedal and associated members, for control- 'ing the operation of the endless belt, Fig. 5 is a side view of the worm, showing its bearing in section, Fig. 6 is a front View of a bracket and an arc-lamp connected there with, Fig. 7 is a side view of the same, Fig. 8 is a perspective view of the printing plate and its supporting frame, and Fig. 9 is a diagrammatic view of the arc-lamps, motor and their circuits.

In the, drawings wherein is illustrated a preferred embodlment of my invention, the numeral l designates pairs of .verticallyl disposed spaccd castings, each of which con prises a short forward upright 2 and a long rear upright 3. For the sake of clearness,r

the rear upright 3. near, its' -center, by a i horizontal section 5. The upper end of each of the rear nprights 3, is provided with a forwardly extendingV section 6 having an annular )ortion 7 connected therewith. as shown. ne of the forward uprights- 2 has a bracket. or support 8, connected therewith,

suitably secured to the 4nient of thepinion 28 muy us shown at. t). The lower ends of the uprights 2 ind` 3 nre connected by transverse rods 10, shown. The bracket 8 has u horizontal portion 1l, upon which is rigidly mounted a :notoil2 of any preferred or well known forni. This motor has its urinaiturc snuit 13. The armature shaft 13 its rear portion journuled through u bracket l5. Whit'. is provided with n cut-out portion s, iti4 for forming :i recess for :i worin 17 formed upon seid armature sluift, :is shown. The bracket 15 has its lower' portion bolted to the rear upri ht 3, as shown :it 18. The bracket 15 has tormed integral therewith an opstanding arm 19, provided au, its upper end with :i journal box Q0 for rotatably holding one end of a connecting shaft 21, the other end of whichr is rotatably mounted Within n journal box 22, which is upright 2l. Rotatebly mounted upon the shaft 2l is avlurgc pinion 2.4, which is rigidly mounted. upon n hub-portion of u small pinion 26, as shown. The pinions 24 and 26 thus rotate together sind engage respectively, small and large pinions 27 and 28. The pinion 27 is rigidly mounted'upon a stud shaft 29, which is rotatably mounted within a. journal box 30 formed upon the vertical portion of the lrztcket 15. This stud shaft is further provided with a u'orxnwvht-.el 3l, 'which meshes with the worin 17. This large pinion Elf-i is splined upon a shaft 32, arranged udjacent to and in end to end relution with the said studishaft. 'The shalt 32 is rotatably mounted within a, journal box 33, supported by a bracket 34 which is rigidly connected with the upright 3. The pinions 27 and 2B are provided upon their adjacent faces with pins 35 und 36, respectively, which are adapted to engage euch other when the pin ion is moved longitudinally of its shaft, whereby the, Si ud shaft 29 and the shaft 32 are locked together. The longitudinal movebe effected by menus of a shifting lever or the like (not shown). From the descril referred lo parts, it is obvious that the rotution of the armature shaft 13 may be inipurted -to the shuft 312, to cuuse the latter lo be minted nt diiierent rates of speed. When the pinion 28 is in engagement 'with thc pinion 2li, thc shaft 32 is driven by the urinuture shaft at low speed.' lVhen the pinion Q8 is disengn 'fed from the pinion 2G and moved longitudinally of its shaft., so

that its pins 3G engage theV pins fl'r'of pinion "3T, the shaft B2 is locked with the shzift 29 und rotgited at high speed.

The outer end of the shufl't 32 hns u bereigenr 37 rigidly mounted thereon, as shown, for meshing with n second bevel-gear 38, which is rigidly mounted upon the lower cud of :L v/erticnlly disposed actuating shut! 39. This actuating shaft has its upper und )tion of the above lower portions rotatably mounted within journal boxes 4() und 4l. respectively. which are carried by brackets 42 und i3 haring rigid connection with the upright 3, ns shown.. The actuating shuft 3S) hns u bevel-geur 4-4 rigidly connected with the u per end thereof, which meshes` with. u bevel'genr 45. This bevel-geur -l is rigidly connected with one end of :i rotary shaft 4G, which is mounted within journal boxes 47 disposed upon the up ier endsof the uprights 3. The longi tu inal displacelnentlot theshaft 4G is prevented by washers 48,;.vrhieh are disposed between the ends of a rdller 49 rigidly mounted upon the shaftit, and said journal boxes 47. A rock-shaft 50 is journaled through the central portions of the sections 5, :is shown, and has brackets 51 rigidly mounted upon the same near its ends and inwardly of the castings l. Each of the brackets 51 comprises an upstanding body portion 52, having its u per free end pro-J vided with a substantial y horizontally disposed cut-out portion 58, and its lower end provided with a. vertically vdisposed cylinrleal portion 54, which 1s preferably cast inte ra with` the body portion 52. The brac ets 51 are provided to adjustably support a rotatable shaft 55, which has its ends disposed within the openings 53. A roller 56 is looselymounted upon the shaft 55 and has trained therebout a. flexible endless belt 57, which is also trained about the roller 4t) and a small roller 58, rotatably mounted between brackets 59. These brackets are inde- 100 pendently vertically adjustabl mounted upon-the uprights 3, in any suits. le manner. By the vertical adjustment. of either of these brackets 59, the corresponding end of tho, roller 58 may be raised, to prevent the lut 105 eral creeping of the endless belt 57 in that direction. The object of having the brackets o] to adjustably. support the shaft 55 and its roller, is to permit of the removul of the print paper und tracing from the machine 11o when desired.'

The cylindrical portion 54 of each oflthe brackets 51 has rigidA connection with a. rod (i0, extending downwardly in a substantially vertical osition for engagement with a head (Si, whie is provided upon itsopposite sides with npertured ears 62. The rear ear 62 is connected Within retractilecoil spring 63, hnving'its opposite end 'cnnected with o, bolt.

($4, which is suitably connected with the rear upright 3, ns shown. 'lJhe forwgird ear 62 'has pivotal connection with a link 65,'piv0ted ut its forward end to nn arm 66,asfshown at .67. This ann is rigidly mountedl upon one 2nd of u rock-'shaft 68, which sjournaledthrough the lower portions of the uprights 2. The rockhuft 68 .has a. lever 69 rigidly connected' therewith near each en as shown, for engaging one end of a pedal 70,

whieh @tends forwardly of the castings l. l);

Vlien the 4pedal 70 is depressed. the rods 06 are oscillated rearwardly and the bracketis 51 are oscillated to more the roller 5G forwardly. whereby the belt .'17 is slackened. Upon the release ef the pedal T0. the springs 63 oscillate the rods reznwardly. which cause tbe oscillation of the brackets 51. Lhereby the belt 57 is placed under proper tension. I

Pairs of brackets 71 are provided. which are bolted as shown at 72. to the sections .3. These brackets serre -to support a top 72S forming: a feed table. Strips 74 are rigidly connected with the inner ends of the brack` ots 71 and rotatably support therebehi'een a feed roller 75. The brackets 71 are each provided with depending arms 70, for rotatably supportingr a roller 77 upon which is mounted the print paper 78; Above and near the brackets 71, are disposed swingir? 1 curved arms 79, which are spaced from eac other, as shown, and rigidly connected at their upper and lower ends by means of T irons 80. Each of the arms 79 is pivotally connected with the annular section 7. b v a pin 8l. The upper end of each1 of the. arms 79 is apertul'ed, as shown at to receive a removable pin 83, which iypassed through an opening formed in the castingr 1. The

, -pins 82 retain the arms 79 in their normal positions. as shown in Fig. 2, and said pins being removable, permit of the oscillation of said arms in a forwardly direction'. The arms 79 together with the T-irons 80, form'- a support for a preferably glass transparent printing plate 84. which is substantially semi-ellipticalin cross-section. as shown. Thisl printing' platefnlay be translucent instead of transparent. The printing plate t S4 is of the proper width to fit snugly be tween the T-irons 80 and engages shockabsorbiney members 85, carried by Said T- irons. The printing: plate S4 engages the endless belt 57. and when in such engage n1ent.as shown in Fig. 2, has its major transverse axis inclined. `as shown. A cylindrical pipe H is horizontally disposed and snitably connected with the annular section 7, as shown at S7. This pipe serves tosupport adjustable brackets 88. which have connected therewith arc-lamps S9. Each of the brackets 88 (sce Fig. 7) has its lower end pre-vided with a semieylindrical cut-out portion 90 for the reception of the pipe 86. A clamp 91 is adjustably connected with the bracket 88 adjacent the cnt-out portion 90. by means of bolts 92. or the like. This clamp has` a curved lip 93 to cooperate with the wall of the cut-out portion Slt) for gripping the pipe 8G. From the description of the above referred to parts. it is" obvious that each of the brackets SS. may be Aoseillated from their normal vertical position to a substantially horizontal position, and that. said bracket may be clamped in a rigid position to th*k pipe Sti at an desired angle. 'hen the brackets HS are oscillated, forwardly. a Suflicient space is alforded to permit of theV clamping the head 90 in a rigid position upon said bracket. The body portion ofthe arc-lamp supports a globe 98, within which are mounted positive and negative carbon's 09 and 100. Owing to the upper portion of the transparent plate 84 being farther removed from the free ends of the carbons than the lower end ot' said plate, all the heat rays from the lamps will strike against" said plate with vsubstantially the same. intensity, avoiding extreme local overheating.lr and breakage by the resultingr uneven cxpansion. No detail description will be given of each of the arc-lamps, as no claim will be `made to the same in this application.

The' automatic adjustment of the carbons 'in tht` arc-lamp` is etl'ectcd by the solenoids 101 and 102, there being suitable connecting means between these solenoitls and said carbons. as is the case in an ordinary arc-lamp. These arc-lalnps are compact in arrange- -anent and owing to the location of the solenoids 101' and 102. said lamps are formed short so that the)r will not occupy too much spaee in the machine. Each are-lamp S9. is provided with a retlector 103. haringr snitable connection with the body portion E14 and extendingr downwardly to engage th'e foot of thef'bracket 8S. The arc-lamps are connected with circuits to be described, and these circuits are controlled by switches 103 and 104. The motor 12,is connected with a circuit to be described. which .circuit comprises suitable wires and a rheostat 107` as shown in Fig. 1. A switch b` is proridcd to control the motor circuit. The feed wires for supplyin,"r current to the said circuits are disposed within the pipe S6. A fan motor 108* is .arranged at one side of the machine and centrally of the annular section 7, as .l

shown. This fan motor is connected with a bracket 108b which is suitably connected with the casting 1. The function of this fan is to drive out of the machine the air heated by the arc-lamps, whereby plate 113 is prevented from becoming too hot. A diagrammatic view of the clrouits for the lamps,` fan motor and motor forms a part of this speciicatiom' Ynd tlie same will,be dc.- scribed in detail hereinafter. The horizontal sections 6 have links 109 pivoted thereto, as shown at 110, and t-hese links are shown inv their lowermost position. The

links 109 have rigidly connected therewith a section` of sheet metal 111, having its lower end bent. upwardly, as shown at 112, to form a receptacle *orreeeivingr the tracing after the saine has. passed through the machine. A sheet metal lid 113 is hinged to the section 111, as shown at 114. This lid normally covers the transparent plate Hl and the arcduinps. but the saine may be oscillated upon its hinged joint to allow aecess to the last referred lo parts. The seetien 111, together with links 109, may also he oscillated upwardly to permit the arc lamps and their brackets to be inclined t0- ward the horizontal.

In Fig. 9 is illustrated the diagrammatic view above referred to. The numeral 115 designates a dynamo for supplying current to the arc-lamps, fan motor and motor. Lead wires 116 and 117 are connected wit-h the dynamo 115, as shown, and the arclarnps are connected with the lead wires 116 and 11T, by means of 'branch wires 118 and 119. The switches 103'i and 104 control the current supplied to the arc-lam s. The fan motor 10S is connected 4with t e feed wire 116 by means of a wire 116 and said fan motor is connected with the arc-lamps, as shown, by means of a4 -wire 117 and the branch wires 117". The motor 12 is connected with 'lead wires 116 and 117, as shown, and the-rheostat 107 is placed in series with the wire 117 for controlling the speed of the motor. It is obvious that the fan motor will he in operation when -current is [lowing through both or either of the arc lam )s 89. It is thought thatthc operation of the above referred to circuit may berend ily understood, and therefore Such operation will not be recited. i i

In the operation of the machine the" print paper and tracing 129 are fed betweenthe feed roller and the endless belt., "glielJ are carried up Vwardly across the print-lng plate and said print paper is made to travel about the print` paper and tracing roller"46, while ,the tracing is conducted'l over the lid 113 and collected within the, recap'.- tucle formed by the sheet metal section 111. It is thus seen that the tracing isfed into the machine and discharged therefrom u on the same side.4 -The operator may slate :en

the endless belt? by proper manipulation of the pedal 70, whereby the print paper and tracing :nav be removed from the machine' or shiftedin position when necessary.

I wish itl ul'i'derstood thatt-he form; of my invention herewith sho'wn and described, is to h`e taken as a' preferred example of the same, and that ecrtain'ehanges in vthe size, shape and arrangement of parts may be resorted to without departingfrom the spirit ofrlny invention or -the scope' of the subjoinedv claims.
